Calculation inputs stay in the browser
Grams to Moles processes formulas, masses, molar masses, and batch entries on your device. The app does not send those entries to a calculation server or save them in local storage or session storage. Refreshing the page starts the app again with its defaults.
The site currently has no accounts, advertising, or analytics scripts. The calculator itself does not set cookies. Copying a result places it on your clipboard; printing and downloading create copies through your browser or device, under your control.
Hosting and request information
Cloudflare hosts and delivers this website. Loading a page involves a web request, which can include your IP address, browser and device information, requested URL, referrer, and request time. Cloudflare may process this information and security-related cookies or similar signals to deliver, protect, and troubleshoot the site. Keeping calculations local does not make a visit anonymous to the hosting provider.
Cloudflare's own handling of information is explained in its privacy policy.
